air conditioning CHEVROLET COLORADO 2007 1.G Owners Manual

Recirculation is only available in the bi-level and
vent modes. It should only be used while in bi-level
and vent modes. Recirculation is not available,
and the light will not come on or ash while in heat,
oor, oor/defog, or defrost modes.
#(Air Conditioning):Press this button to turn
the air conditioning system on or off. An indicator
light on the button will come on to let you know
the air conditioning is activated. When the system
is on, this setting cools and dehumidies the
air entering your vehicle.
The air conditioning will not function if the fan is
turned off.
You may notice a slight change in engine
performance when the air conditioning compressor
shuts off and turns on again. This is normal.
The system is designed to make adjustments to
help with fuel economy while still maintaining
the selected temperature.The air conditioning system removes moisture
from the air, so you may sometimes notice a
small amount of water dripping underneath
your vehicle while idling or after turning off the
engine. This is normal.Defogging and Defrosting
Fog on the inside of windows is a result of high
humidity (moisture) condensing on the cool
window glass. This can be minimized if the
climate control system is used properly. There
are two modes to clear fog or frost from your
windshield and side windows. Use the defog
mode to clear the windows of fog or moisture and
warm the passengers. Use the defrost mode to
remove fog or frost from the windshield more
quickly. For best results, clear all snow and
ice from the windshield before defrosting.
179

Turn the mode knob on the climate control panel
clockwise to select the defog or defrost modes.
/(Floor/Defog):This mode directs the air to the
windshield, the side window outlets, and to the oor
outlets. When you select this mode, the system
runs the air conditioning compressor unless the
outside temperature is near freezing or below.
Recirculation is not available in this mode.
0(Defrost):This mode directs most of the
air to the windshield, and the side window outlets.
When you select this mode, the system runs
the air conditioning compressor unless the
outside temperature is near, or below freezing.
Recirculation is not available in this mode.
Do not drive the vehicle until all the windows
are clear.
Outlet Adjustment
Use the thumbwheel on the outlets to change the
direction of the air ow.
Lift up or push down on the thumbwheel located
in the center of the outlet to direct the air up
or down, or slide the thumbwheel to the left or
right to direct the airow from side-to-side.
Operation Tips

Clear away any ice, snow or leaves from the
air inlets at the base of the windshield that
may block the ow of air into your vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of
objects to help circulate the air inside of your
vehicle more effectively.

DIC Warnings and Messages
Messages are displayed on the DIC to notify the
driver that the status of the vehicle has changed
and that some action may be needed by the driver
to correct the condition. Multiple messages may
appear one after another. The messages are
displayed for several seconds each.
Some messages may not require immediate
action, but you should press and release the
trip odometer reset stem to acknowledge that you
received the messages and to clear them from
the display. Each message must be acknowledged
individually.
Some messages cannot be cleared from the
DIC display because they are more urgent.
These messages require action before they
can be cleared. You should take any messages
that appear on the display seriously and remember
that clearing the messages only makes the
messages disappear, not correct the problem.
The following are the possible messages that can
be displayed and some information about them.
AC (Air Conditioning) OFF
This message displays when the engine coolant
temperature is too high and the air conditioning
in your vehicle needs to be turned off. SeeEngine
Overheating on page 348andClimate Control
System on page 177for more information.
This message displays along with the ENG HOT
message.
ABS (Anti-Lock Brake System) FAULT
This message displays if there is a problem
with the Anti-Lock Brake System (ABS). Check
the ABS as soon as possible and have your
vehicle serviced by your dealer. SeeBrakes on
page 357andAnti-Lock Brake System Warning
Light on page 190for more information. Press
and release the reset stem to acknowledge
the message and clear it from the display.
BRAKES
This message displays if there is a problem with
the brakes. Check the brakes as soon as possible
and have your vehicle serviced by your dealer.

Radiator Pressure Cap
Notice:If the pressure cap is not tightly
installed, coolant loss and possible engine
damage may occur. Be sure the cap is
properly and tightly secured.
SeeEngine Compartment Overview on page 332
for more information on location.
Engine Overheating
A coolant temperature gage is on the instrument
panel. SeeEngine Coolant Temperature Gage
on page 191.
The air conditioning might stop working if the
engine is too hot. This is normal and helps
cool the engine.
If Steam Is Coming From Your Engine
{CAUTION:
Steam from an overheated engine can
burn you badly, even if you just open the
hood. Stay away from the engine if you
see or hear steam coming from it. Just
turn it off and get everyone away from
the vehicle until it cools down. Wait until
there is no sign of steam or coolant
before you open the hood.
If you keep driving when your engine is
overheated, the liquids in it can catch re.
You or others could be badly burned.
Stop your engine if it overheats, and get
out of the vehicle until the engine is cool.
Notice:If your engine catches re because
you keep driving with no coolant, your vehicle
can be badly damaged. The costly repairs
would not be covered by your warranty.
348

If No Steam Is Coming From
Your Engine
If you get an engine overheat warning but see
or hear no steam, the problem may not be
too serious. Sometimes the engine can get a
little too hot when you:
Climb a long hill on a hot day.
Stop after high-speed driving.
Idle for long periods in traffic.
Tow a trailer. See “Driving on Grades”
underTowing a Trailer on page 306.
If you get the overheat warning with no sign
of steam, try this for a minute or so:
1. In heavy traffic, let the engine idle in
NEUTRAL while stopped. If it is safe to
do so, pull off the road, shift to PARK (P)
or NEUTRAL and let the engine idle.
2. Turn off the air conditioning.
3. Turn on your heater to full hot at the
highest fan speed and open the windows
as necessary.If you no longer have the overheat warning,
you can drive. Just to be safe, drive slower
for about 10 minutes. If the warning does not
come back on, you can drive normally.
If the warning continues, pull over, stop, and
park your vehicle right away.
If there is still no sign of steam, idle the engine for
three minutes while you are parked. Push down
the accelerator until the engine speed is about
twice as fast as normal idle speed for at least
three minutes while you are parked. If you
still have the warning, turn off the engine and get
everyone out of the vehicle until it cools down.
You may decide not to lift the hood but to
get service help right away.

The letter R means radial ply construction; the
letter D means diagonal or bias ply construction;
and the letter B means belted-bias ply
construction.
(E) Rim Diameter:Diameter of the wheel in inches.
(F) Service Description:These characters
represent the load range and speed rating of the
tire. The load index represents the load carry
capacity a tire is certied to carry. The load index
can range from 1 to 279. The speed rating is the
maximum speed a tire is certied to carry a load.
Speed ratings range from A to Z.
Tire Terminology and Denitions
Air Pressure:The amount of air inside the tire
pressing outward on each square inch of the tire.
Air pressure is expressed in pounds per square
inch (psi) or kilopascal (kPa).
Accessory Weight:This means the combined
weight of optional accessories. Some examples of
optional accessories are, automatic transmission,
power steering, power brakes, power windows,
power seats, and air conditioning.Aspect Ratio:The relationship of a tire’s height
to its width.
Belt:A rubber coated layer of cords that is located
between the plies and the tread. Cords may be
made from steel or other reinforcing materials.
Bead:The tire bead contains steel wires wrapped
by steel cords that hold the tire onto the rim.
Bias Ply Tire:A pneumatic tire in which the plies
are laid at alternate angles less than 90 degrees
to the centerline of the tread.
Cold Tire Pressure:The amount of air pressure
in a tire, measured in pounds per square inch (psi)
or kilopascals (kPa) before a tire has built up heat
from driving. SeeInation - Tire Pressure on
